Application filed September 29', 1921. Serial No. 504,164.

the brush head audits handle so that there shall be both a rigidconnection and' one which will permit easy separation of head andhandle.v This invention also includes the idea of so connecting the headand handle as to eliminate the'tendency of torsion to cause the breakingof the holding means connectinghead and handle'an'd prevent therotationof the handle with relation to the head.

My invention further resides in the combination, construction andarrangement of parts illustrated in the accompanying drawing, and whileIhave shown therein, preferred embodiments, I desire the same tobeunderstood as illustrative only and not as limiting my invention, v

In the drawing attached hereto and forming a part hereof:.- Fig.1 is aside'elevat'ion of a brush head with a fragmentary. showingof the handleto show the shape of the brush head and to illustrate the manner ofattaching the two elements.

Fig. 2 is a plan view of the structure shown in Fig. 1.

Fig. 3 is a perspective view of the handle member shown in' Figs. 1 and2 together with the means for attaching the handle to the brush head orbody and preventing the rotation of the parts thereof with respect tothe body portion. 7 i

Fig. 4- is a fragmentary showing of the brush head illustratingasimplified con-.

struction for use in brushes in which it is.

while 4 designates a U-shaped fastening member passed through the bodyand the ends of the handle. As shown in Fig. 3, the handle 2 is U-shapedand is provided in or near its ends with notches 5, while there endsperforations 6, adapted to receive :the ends of the U-shaped fastening,member 4. A notch 7 of any desired shape may be provided in thebrushbody for the insertion of a: small implement for the removal of thefastening member 4.

It will be obviousfrom the foregoingthat when the pin 3 is I passedthrough the body member 1, and the handle member 2 1s mare provided,somewhat removed'from the serted into the perforations in the end of thebody member until the notches 5 closely engage said pin, itwill be,almost out of the question-for the parts of the handle'Q to rotate inthe openings'ln the body'member because of the close fit of the openings5 and the pin 3. Alsothe fastening member 4 "fits closely in openings inthe body member and in openings 6 in the handle member, .thus alsoassisting in preventing rotation of these members in relation to thebodyimemher as well as preventing withdrawal of the handle memberfrom-the body member.

In brushes in which it is not necessary to 7 provide against soim'uchftorsional strain the structure can be simplifiedas showirinFig.4, by omitting the fastening member 4, and its cooperating perforationsin brush body and handle and substituting forthe notches 5-corresponding perforations a little removed' from the ends'ofthe handle..By

then insert-ing'a pin 3, which' closely fits these perforations;rotation .of'the handle parts because ofthe-torsional strain will beprevented, andthe handle will be unable to break the pin. omits theadded advantage, to be obtained from the use ofthe member 4, whichcooperates with pin 3 in preventing the destructive effects of thetorsional strains. It is obvious that, if desired, member 4 may be usedin the form illustrated in Fig. 4.

As shown in Figs. 1 and 4, the brush body Of course, this constructionThe surface defined by the bristle ends ,is

also curved so that the parts are properly arrangedto serve mostefficiently in all situations. The central, curved part Wlll serve forcleaning angles while the plane portions will serve for cleaningverticalmwalls or besides the spokes.

the bottom of bath tubs and the like. These parts Will also serve veryeffectively for the cleaning of various parts of automo il s t will beeen f om the foregoing that not only is the connection between the brushhandle and head veryeiiicient and effective and easily connected anddetached, but the brush head itself; is so shaped that it can be readilyused to Wa h in many difficult lo ation the o tuse angle twee the par sf the head having. en found t e th most sa sfa ory one which could e chsen:

It is, of oursenndcrstood ha the pecific descriptio of stru ture setforth above may be I departed from Without departing from the spirit ofmy invention as set forth n h s spec fic tion and the appended cla msvHaving now described my invention, I c aim a 1. In a construction of thecharacter de scribed, a body having a pair of holes there.- in, a handlecomprising a, co-operating pair of arms adapted to be inserted into saidh s, Said arms having transverse notches the ends thereof and a pinpassing through the body and the notches in the ends of the arms.

2, In a construction of the character described, a body having a pair ofholes therein, a handle comprising a co=operating pair of arms adaptedto be inserted into said h sai rms having transverse holes nea th n s'holfeof and a fastener passing through the body theho es in the arms.

3.. n a c ns ruction of the character described, a body having a pair ofholes there in, a handle comprising a co-0perating pair of arms adaptedto be inserted into said holes, said arms having transverse notches inthe ends thereof, a pin passing through thebody and hr ugh the notchesin the ends of the arms, transverse holes near the ends, of the arms,and a fastener passing through the body and through the holes in thearms to holdthe two together.

4. In a brush, a body having a pair 01 substantially-parallelholes'therein, a handle having a pair of arms extending into said holesand themselvesbeing provided at their ends with a pair of notches andnear their ends With a pair of perforations, a pin exending through thebody and the notches in the arms to assist in preventing rotation ofsaidarms insaid body,'and.fastening means extending through the body andthe perforations to prevent the separation of said body and arm..

5.. Ina brush, a body having a pair of substantially, parallel,longitudinally extending holes, a U-shaped handle having its armsextending into "said holes, said arms having adjacent their ends holesextending in substantially the same direction transversely of the axesof-the arms,;a nd a U- shaped fastening means extending through the bodyand the arms to hold the parts in assembled relation and assist inpreventing rotation of each arm in its respective hole.

6. In a brush, a body having a pair of substantially parallel,longitudinally extendingholes in one end of said body, a

U-shaped handle having its arms extending .into said holes, said armshaving adjacent their ends holes extending in substantially the samedirection and transversely to the holes inthe body, and fastening meansextending throughthe body and arms to hold the parts in assembledrelation and assist in preventing the rotation 01" the arms in theirrespective sockets.

In witness whereof, I hereunto subscribe my name to this specification.
